Common Rose-Mallow

<em>Hibiscus moscheutos</em>, commonly known as the common rose mallow, is a flowering plant in the family Malvaceae. Native to wetlands and marshy areas across eastern North America, this herbaceous perennial has been introduced and naturalized in parts of Brazil, Romania, and Taiwan. The species typically inhabits freshwater marshes, riverbanks, pond margins, and moist meadows, thriving in full sun to partial shade conditions. It produces large, showy flowers that can reach up to 30 centimeters in diameter, typically displaying white, pink, or red petals with a distinctive dark center. The plant can grow up to 2.5 meters in height under favorable conditions. Common rose mallow is assessed as Least Concern on the IUCN Red List, reflecting its wide distribution and stable populations across its native and introduced ranges. It tolerates flooding and temporarily waterlogged soils, making it well adapted to riparian ecosystems. The species is pollinated primarily by bees and other large insects attracted to its prominent blooms. Biological traits such as average lifespan, typical body measurements, and diet remain poorly documented in standardized ecological databases. In cultivation, it is widely grown as an ornamental plant, valued for its dramatic flowers and adaptability to garden settings.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
